WebThe reduction half-reaction occurs at the cathode, whereas the oxidation half-reaction occurs at the anode. The entire process, otherwise non-spontaneous, is driven by the electromotive force. However, sometimes the solvent molecules or the electrodes may also participate in the electrolysis instead of the ions furnished by the electrolyte. WebApr 13, 2024 · The oxidized species (M (n+1)+) triggers polyolefin surface oxidation and subsequent C−C bond cleavage, which causes the ion to turn back to its reduced state M n+. Lastly, the metal ion (M n+) returns to the electrode surface, oxidizing it again due to the externally applied potential. [21] Two factors are critical in the MEO process: the ...
